In the Forest of Isle-Adam around the Abbaye du Val

This hike is a shorter version of the hike called "The Isle-Adam National Forest and its southern edge". The route, with sections through the forest and paths across fields and meadows, offers beautiful woodland scenery and sweeping views of the surrounding countryside thanks to the gently rolling terrain.

Description of the walk

Depart

The hike starts at the small car park on Rue du Pavillon de Chasse in Mériel (Val d'Oise).

Head towards the northern end of Rue du Pavillon de Chasse. Take the path that continues along it, go through the gate and continue straight ahead until you reach the road (D9).

(1) Cross the road, pass the entrance to the Abbaye du Val and continue along the path running alongside the estate's boundary wall. At the junction with a farm track, turn right and continue to the fork 100 metres further on, where you continue straight ahead along the path running alongside the field. This path climbs, then descends into a hollow at the junction with a forest road.

(2) Turn right towards the Marais de Stors Regional Nature Reserve (signposted).
Follow the Marais de Stors, then climb a hill where you pass under the arch of a ruined bridge and arrive at the top of the hill at a junction with a path that you follow to the right.

(3) About a hundred metres further on, you will come to a signposted path coming from the left and turning in front of you.

GR® signposting (red and white)

Continue straight ahead. The path winds along the edge of old quarries. After about two kilometres, it joins a wide forest road.

No signposting

(4) Follow this forest road to the left (let theGR® turn right). You will reach the Carrefour Capitaine (signpost in the centre). Continue straight ahead. The road runs along the left-hand side for two to three hundred metres, passing an area undergoing regeneration.

(5) Continue straight ahead, slightly to the left, on the Capitaine forest road. At the second junction, turn right onto the marked trail.

PR® signpost (yellow).

(6) Continue along this winding path through the forest until it ends at a paved road passing between two large stone pillars. On your left is the entrance to the Isle-Adam Dog Club.

No signposts

(7) Turn right onto the Bois Franc forest road, which is paved for a few hundred metres, and continue straight ahead to the Carrefour Vicaire (signpost in the centre) where you will see some rocks.

(8) Now follow the Vicaire road (second on the right) between forest plots 76 and 77. Turn left at the end of this road, at the corner of plot 76, then left again at the next crossroads. A hundred metres further on, you will come to the junction with the Bois Franc forest road, which is now marked GR®.

GR® signposting (red and white)

Turn right. At the end of the forest road, cross the bridge over the N184. You will arrive at the Porte Baillet crossroads.

(9) Continue diagonally to the left of plot 70 until the next junction at plot 41, where you turn right.

No signposts

Go to the second crossroads and turn right (plot 69). Three hundred metres further on, cross the D9 and continue to the end of this lane, then turn left onto the path that takes you to a crossroads where you join a PR®.

PR® signpost (yellow).

(10) Turn right, the path crosses a paved road and, from there, becomes a grassy track crossing a cultivated area. The track turns right after about 100 metres.
Continue straight ahead to the edge of the forest where the path enters the woods. It turns left immediately and follows the edge of the woods to a crossroads in a hollow where it joins a GR® marked path.
Turn right onto the path, following either the yellowPR® markings or the red and white GR® markings. The path winds through the woods. It emerges and ends on a farm track closed by a metal gate near the D9 and a bridge over the N184.

No signposts

(11) Take the tarmac road on the left that climbs towards the N104. After crossing the bridge over the N104, turn right onto the farm track closed by a metal gate, then, about 50 metres further on, turn left onto the grassy farm track that climbs through the fields.
You can see the bell tower of the church in Villiers-Adam in the distance behind the trees. Continue, cross a copse, pass a small stud farm and, at the crossroads, turn right onto the rough road lined with telephone poles.

(12) At the next T-junction, turn right onto the farm track. After about 50 metres, turn left in front of a solitary tree onto the track that leads to Rue de Mériel in Villiers-Adam.
Take this road on the right. It will take you to the exit of Villiers-Adam in front of an old brickworks.

(13) Cross the N184 bridge and, after crossing the slip road, immediately turn right onto the narrow pedestrian passageway that leads to the southern end of Rue du Pavillon de Chasse de Mériel, where you will find the car park.

The walk is now complete.

A beautiful route that reconciles me with the forest of Isle Adam. I remembered a previous walk with long, monotonous straight stretches on very wide paths. Here, most of the time you're on narrow trails that wind through the vegetation.
The end and the return via Villiers-Adam are on tarmac, but you have to come back somehow! Perhaps do the route in the opposite direction to do the tarmac at the beginning 😊 You cross national roads three times, which isn't the most pleasant, but the noise of the cars is quickly forgotten in the forest.

Beautiful hike through the woods. Very few paved roads, just enough to get from one trail to another. A must-do!

Beautiful route near Paris. Beautiful forest and countryside with cornfields, close to the Francilienne motorway and the A16 junction, which causes some noise.
All in all, a lovely ride!

I only use the GPS track and it was perfect.
A beautiful hike in the forest.
Personally, my GPS showed me a good kilometre more at the end.

Very pleasant, shaded and easy hike. The path that goes around the Stors marsh is really lovely.
There is also a lovely path on the Baillet side. And above all, the hike involves very little walking on roads. I highly recommend it.

A very beautiful trail, pleasant to walk along, mostly in the forest. Between points 3 and 4, you pass over a quarry area. At this point, it is worth taking a moment to descend one of the paths leading down to admire the landscape of these cliffs, from which stone was once extracted.

A lovely little hike. Not very difficult, and can be done in the middle of summer as it is mostly in the forest or under the trees.

Only comment: the Stors Marsh Regional Nature Reserve, which the route bypasses at the start, is very pleasant and interesting. It is worth slightly altering the route at the start of the walk. Otherwise, this is an easy and pleasant walk in hot weather as the route is often shaded.

Hello leonspontex, and thank you for your comments.

Please note that we understood the instruction "Leave the GR and turn right" to mean "Leave the GR and turn right", which is a 2 km detour...

I have moved this instruction after the one saying to turn left: I think this makes it clear.

Enjoy your hike, which is varied with pretty paths, although there is often traffic noise.
Be careful at the sign saying "Leave the GR and turn right", we understood it as "Leave the GR and turn right", which resulted in a 2 km detour...

A very beautiful hike. In this beautiful autumn weather, we encountered many people in the forest: walkers, runners, cyclists, and horse riders. We felt that the route was much longer than the 15.7 km indicated in the description (admittedly, we took a few detours to pick up chestnuts and walnuts, but my GPS still showed more than 18 km)
